Pulling an allnighter for school post-op

So I pulled/ am pulling an all-nighter trying to get caught up on my school work after the surgery. Its because of procrastination as my concentration has been all over the place since I am not taking my adderall.  My surgeon said my SR script probably wouldn't work very well and would go through my system quickly but I haven't been able to get into my PCP to get a new none SR script. So last night as I am studying for the first time I decided to take one to see if it would help. Well I am still wide a wake and getting a lot down which I am happy with but surprised by. 

So to the actual question. If am I up for over 24 hours do I start doing my protein/water/pureed regiment over after a certain period of time from my last meal?

Well, I would certainly drink if you're awake.  I eat about every three hours, so I would be eating if I was up all night, too.

Thank you. I have been drinking lots of water. About 5:00am I had a shake and vitamins. I am going to eat my pureed food in a few. I guess if I am going to continue to stay up for the day I should stay on track.
